When he was diagnosed with ASD, was it through the school or through your medical provider? Did they talk any more about therapy, like ABA therapy, and is it covered under your medical insurance? My son is 7, and he gets 12 hrs of ABA therapy a week. They mainly go through social skills, and they practice a lot of verbal communication. So with your son, it depends on why he doesn't have friends. Is it because there's no one he can relate to, like all the other boys are talking about Pokemon, and he doesn't want to? Or he does want to do stuff with other kids, but he gets stuck trying to communicate (feels shy, gets tongue tied, etc?)
